My new Pond dam has some cracks forming along the top ridge that I am concerned about. I was finally able to coral the builder and he's planning on looking at it tomorrow. I've also had, what appears to be a leak along the bottom but my builder seems to think it may be a natural spring but I am skeptical. I have no experience with any of this but I did notice on a Youtube channel, LetsDig was repairing a leak on a dam that had a crack....and it looked pretty much like the ones I've got, If anyone has any experience, please share if you can. Thanks
